IMPROVEMENT IN METAL CANS.

Specification forming part of Letters Patent No. 198,658, dated December 25, 1877 application filed A octoter 31, 1877.

To all whom fit may concern:

Be it known that we, JosEPH W. MILLER and BERNARD COLL, of Baltimore, in the county of Baltimore and State of Maryland, have invented a new and useful Improvement in Metal Cans, which is fully set forth in the following speoication and accompanying drawings, in which- Figure l is a side View of the improved can. Fig. 2 is a section view through x y, Fig. 1. Fig. 3 is a perspective view, showing the head partly soldered in. Fig. 4 is a View of the blank from which the body of the can is made. Fig.`5 is a section of same through the line z z. Fig. 6 is a view of the head.

Our invention relates to an improvement in that class of square tin cans employed for packing and transporting raw oysters, which usually have V- shaped notches out at the corners,

and the ends bent over on the outside of each head, thusforming iianges, to which the heads are soldered. Defective joints are thus liable to be made at the corners. Our invention overcomes this difculty, and has other advantages, which will be hereinafter set forth.

Our invention will irst be described in connection with the drawing, and then pointed ont in claim. Y

A represents the body of the can; B, the head, the corners b of which are clipped 0E suicient to permit them to be placed in position. -The body is rst blanked out, and the flange c formed along the edges which are to constitute the ends of the can. At the points where the corners Willocour, when the blank is formed into the shape of a square can, the formation of the flanged edge is omitted, as

4shown at d, by which the occurrence of splits in the can-corners is avoided. The can-body of the corners,

is seamed, preferably, at one and the heads rest on the seat formed by the iange c, and are soldered, as shown at e, either by the ordinary soldering-iron or by a gas-jet, the operation of Asoldering being effected more rapidly-and with economyin the use of solder, and with lessv liability of an imperfect joint, than is attainable by ployed. By our formation of can and method of securing the heads the can may be tllled after one head has been soldered in, andthe top head -then placed in positionand soldered, thus dispensing entirely with the usual cap, by which an additional saving is effected.

Having described our invention, we claim and desire to lsecure by Letters Patent- The improved can herein described, having on the ends the outwardly-projecting ange c, y

stopping short of the corners, forming on the inner sides seats, upon which the heads B rest,

the corners of the can being uniianged, the solderbeing applied as shown and described.
